I just recently changed my oil to amsoil 5w-30 sl rated 25k oil which is around 2-3 years old. I also added a quart of redline 5w-30 and 5 oz of LC. Its a acura 2003 3.5 RL engine my question is when I check my dispstick for oil I see small air bubbles on it and I've never seen it before when I run mobil/redline is this normal or am I just going crazy for no reason?
